Answer:6
Step-by-step explanation:
from Pythagoras principle we get
x=√(10^2-8^2)
x=√(10x10-8x8)
x=√(100-64)
x=√(36)
x=6
Answer:
x= -6 | I only have an answer for #7 but you should use a website called Symbolab :)
Step-by-step explanation:
x+16+x+12+2x+15=19
<em>group like terms: </em>
4x+43=19
<em>subtract 43 from both sides:</em>
4x+43=19
-43 -43
<em>simplify</em>:
4x=-24
<em>divided both sides by 4:</em>
x=-6
Answer:
10x² - 9x
Step-by-step explanation:
(10x² - 10x - 6) + (x + 6)
10x² - 10x - 6 + x + 6
10x² - 9x - 6 + 6
10x² - 9x
Answer:
75.36
Step-by-step explanation:
C= 2 pi r
c= d pi
c= 24*3.14
c= 75.36
250 in the account
3%x7=21%
0.21 times 250 = 52.5
250 + 52.5 = 302.5
